Specification of Letters Patent.

Patented Aug. 24, 1909'.

Application led January 20, 1903;, Serial N o. 411,829.

To all 'whom it may concern:

Be it known that l, PETER WEBER, aV citizen of the United States, and 4a resident of Orange, in the county of Essex and State of New Jersey, have made certain new and 'useful Im rovements in Phonographs, of which the fol owing is a description.

My invention relates to a phonograph havinginterchangeable means for changing the relative speed of the feed screw with respect to the mandrel in a definite ratio so as to adapt the phonogra h, when provided with the ordinary sound 4oX carrier driven from the feed screw in the usual manner, to operate upon phonograph sound records having either one hundred or two hundred threads to the inch, or sound records bearing any other definite relation to each other as regards the pitch thereof.

t comprises improved'means for gearing together the man( v so thatI the relative speeds thereof may be varied by a very simple, change of gearing, the change gearing being added to the frame 'of an existing honograph adapted to oper` ate upon recor s having one lhundred threads to the inch or any other single definite gear ratio between the mandrel and the feed screw shaft, the frame and oth er'existing elements of the eXistink machine bein changed by my invention as ittle as possible.

The invention consists of the features hereinafter set forth and claimed.

Reference is hereby made to the accompanying drawings of whichi Figure 1 is a plan view of a phonograph of well-known form to which my invention is applied and Fig. 2 is an end elevation of the same.

Corresponding parts are designated by the same reference numerals in both views.

The phonograph shown comprises a base o1' body 1, formed with an u right 2 upon which 1s rotatably supported tlie shaft 4 carrying thc mandrel 5, to which'is secured a drive pulley 8 adapted to receive the belt from the phonograph motor. The feed screw shaft 7 'is also rotatablyfsunported and is provided with a spur gear 9 and formed with gear teeth of considerable width, as shown. A spur gear 10 is rotatably` mounted upon a longitudinally movable pin 11, said pin being )rovided with a head 12, and being supporte in an opening formed rel and feed screw shaft,

ed thereto in the upright 2, in which it may be secured to said pin in any suitable manner, as by set screw 24.

When'the parts are in the positions shown in full lines, Fig. 1, the feed screw shaft 7 is driven from the mandrel shaft 4 through the gears 6, 10 and 9, and these gears are so pro- 70 portioned that the speed ofthe feed screw shaft will be suitable for feeding the sound box'carriage 14 at a suitable speed for operatingupon sound records having' one hundred threads to the inch. set screw 13, the pin 11 carrying the gear 10 may be moved from the osition shown in full lines, Fig1, to the position shown in dotted lines, in which position the gear 10 Will remain in engagement with the gear 9, but will ybe brought out of engagement Withthe gear 6 and into engagement with the gear 26, and

the feed screw shaft will theri be driven from the mandrelshaft through-the gears 22, 25,

26, 10 and 9, and these gears are so pro or- 85 tioned that tlie speed imparted to the eed screw shaft will be suitable for operatively feeding the carriage 14 with respect to a sound record having two hundred. threads to the inch. The pin 11 may be held in this 90 position by the set screw/'13.

It will be noted. that the frame of the existing phonograph is made use of unchanged, except that the prolonged sliding stud 11 carrying sliding intermediate gear 10 is made 95 use of in place of the short iixed Stud carrying the intermediate gear .in theusual thread machine. Also, the-wide toothed gear 9. of the feed screw shaft is substituted for the narrow construction, and the prolonge(L center 3 for the mandrel shaft 4 is substituted. for the ordinary short center usual in this location. Also, two gears 6 and 22 are placed on the mandrell shaft instead of gear. On the prolongation ofthe center 3 the frame carrying the gears 25 and. 26 vis sleeved, as above described.
